# WiToKit

Welcome to `WiToKit`, a Python toolkit to download and generate preprocessed Wikipedia dumps for all languages.
WiToKit can be used to converts a Wikipedia archive into a single .txt file, one (tokenized) sentence per line.
*Note: WiToKit currently only supports `xx-pages-articles.xml.xx.bz2` Wikipedia archives corresponding to articles, templates, media/file descriptions, and primary meta-pages.*
## Install
After a git clone, run:
```bash
python3 setup.py install
```
## Use
### Download
To download a .bz2-compressed Wikipedia XML dump, do:
```bash
witokit download \
--lang lang_wp_code \
--date wiki_date \
--output /abs/path/to/output/dir/where/to/store/bz2/archives \
--num-threads num_cpu_threads
```
For example, to download the latest English Wikipedia, do:
```bash
witokit download --lang en --date latest --output /abs/path/to/output/dir --num-threads 2
```
The `--lang` parameter expects the WP (language) code corresponding
to the desired Wikipedia archive.
Check out the full list of Wikipedias with their corresponding WP codes [here](https://en.wikipedia.org/wiki/List_of_Wikipedias).
The `--date` parameter expects a string corresponding to one of the dates
found under the Wikimedia dump site corresponding to a given Wikipedia dump
(e.g. https://dumps.wikimedia.org/enwiki/ for the English Wikipedia).
**Important** Keep num-threads <= 3 to avoid rejection from Wikimedia servers
### Extract
To extract the content of the downloaded .bz2 archives, do:
```bash
witokit extract \
--input /abs/path/to/downloaded/wikipedia/bz2/archives \
--num-threads num_cpu_threads
```
### Process
To preprocess the content of the extracted XML archives and output a single .txt file, tokenize, one sentence per line:
```bash
witokit process \
--input /abs/path/to/wikipedia/extracted/xml/archives \
--output /abs/path/to/single/output/txt/file \
--lower \ # if set, will lowercase text
--num-threads num_cpu_threads
```
Preprocessing for all languages is performed with [Polyglot](https://github.com/aboSamoor/polyglot).
### Sample
You can also use WiToKit to sample the content of a preprocess .txt file, using:
```bash
witokit sample \
--input /abs/path/to/witokit/preprocessed/txt/file \
--percent \ # percentage of total lines to keep
--balance # if set, will balance sampling, otherwise, will take top n sentences only
```
